Abstract	Quasar outflows are important for their feedback on galaxy evolution and blackhole growth. These outflows are observed as broad UV absorption lines (BALs) inquasars, reaching velocities >0.1c. In radiative acceleration models,UV-absorbing gas must be shielded by X-ray absorbing gas to reach suchvelocities and, typically, BAL quasars are indeed X-ray-weaker than non-BALquasars. However, recent observations are shaking our understanding on how theX-ray and UV absorbers are connected. We propose to re-observe with XMM-Newtonthree z~2 quasars that did not display UV absorption at the time of the firstXMM-Newton observations, but that have recently developed new BAL troughs. Theseobservations will allow us to constrain, for the first time, the X-ray/UV connection on newly emerged BALs.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
